Techlore Interview (BusKill, Interdiction, and OpSec)

By Michael Altfield, on December 9th, 2025
Michael Altfield Techlore Interview

I’m super happy that Techlore invited me on their YouTube channel to talk security and privacy 😀

Henry was mostly interested in my work with BusKill (an open-source dead man switch), but our conversation ran a gamut of issues regarding security and privacy — including

How to mitigate State-sponsored interdiction attacks, minimizing attack surfaces of mobile phones with broadband processors, the threats of AI “identity verification” systems on privacy, and much more

Enabling SELinux strict on RHEL5

By Michael Altfield, on July 6th, 2009

I’ve been playing around with SELinux at work recently. Not surprisingly, I was struggling to get SELINUXTYPE=strict to work properly. Unfortunately, all “google results for ‘enabling selinux strict’ would return were dead ends. People would enable selinux strict, kernel panic, and ‘fix’ it by disabling selinux.

Well, a co-worker of mine *was* able to successfully enable selinux’s strict policy on RHEL5 (CentOS 5). He gave me this guide to post to the world for others to see how (thanks Mykola):
